### Question: What causes Swimmer's ear?
### Response: Swimming in polluted water can lead to swimmer's ear. Water-loving bacteria such as Pseudomonas, as well as other bacteria or fungi (in rare cases), can cause ear infections.
Other causes of swimmer's ear include:
Inflammation and irritation of the bone and tissues at the bottom of the skull (malignant otitis externa) Scratching the ear or inside the ear Getting something stuck in the ear
Trying to clean wax from the ear canal, especially with cotton swabs or small objects, can irritate or damage the skin.
